About the Esp32-desk buddy PCB

Esp32-desk buddy is an open source ESP32 PCB design by etrigo-cmiygl, published on GitHub. It is a board, with 25 components from 11 distinct parts.

Its main chip is the ESP32-WROOM-32 DevKit, from the ESP32 family. By type, the board carries 9 capacitors, 6 resistors, 5 switches, 2 connectors, 1 transistor and 1 buzzer.

It belongs with the displays & leds and retro computing designs in this gallery.

From the project

ESP32 desk companion with 8 retro games, Spotify now-playing with album art, a focus timer, and a clock/weather display on a 1.54" colour TFT.

Generated schematic for the ESP32 desk buddy. Open deskbuddy.kicadpro` in KiCad, then open the schematic from the project tree.

Written in the KiCad 6/7 schematic format, which KiCad 7, 8 and 9 all open (newer versions will offer to migrate it — say yes, then save).

All symbols are embedded in the file itself, so there are no external symbol libraries to install and nothing to link up. The parts are drawn as simple generic symbols rather than pulled from the standard libraries.

Esp32-desk buddy: common questions

What microcontroller does the Esp32-desk buddy use?

The Esp32-desk buddy is built around the ESP32-WROOM-32 DevKit, from the ESP32 family.

How many components are on the Esp32-desk buddy?

25 components, from 11 distinct parts. The full bill of materials is listed on this page.

Where can I download the Esp32-desk buddy design files?

From the etrigo-cmiygl/esp32-desk-buddy repository on GitHub, which has the schematic; the links under Design files point to each one.

Can I use the Esp32-desk buddy design in my own project?

The repository has no license, so all rights stay with etrigo-cmiygl. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Esp32-desk buddy without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
